Description

Technical Field

[0001] This utility model relates to a heating element, specifically a high-temperature resistant built-in heating element for tobacco products, belonging to the field of tobacco product heating technology. Background Technology

[0002] In existing technologies, the built-in induction heating element typically comes into direct contact with the filter tip, as disclosed in Chinese Patent Document CN117770507A. While this design avoids the problems associated with manually inserting the heating element, the heating element reaches high temperatures during operation, and the filter tip material is not heat-resistant. Therefore, in practical use, the filter tip's lifespan is extremely limited; the filter tip is also prone to decomposition under high temperatures, affecting the taste. Furthermore, in this patent, the induction heating element is inserted into the tobacco and is encased in tobacco without any other auxiliary fixing structure, resulting in poor stability. Therefore, further improvements are needed. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a high-temperature resistant built-in heating element for tobacco products, which is set separately from the filter tip to prevent heat transfer to the filter tip, extend the service life of the filter tip, and improve the installation stability of the heating element.

[0004] A high-temperature resistant tobacco product with a built-in heating element includes a tube body, in which a filter section and a tobacco section are built-in; a sensor and a heating element are disposed within the tobacco section, and a heat insulation component is disposed within the heating element; one end of the heat insulation component is connected to the filter section; and the smoke-generating material is located between the heating element and the tube body.

[0005] Furthermore, an mounting platform is arranged around the inner side of the front end of the tobacco segment; the front end of the heating element abuts against one side of the mounting platform; the sensor is located on the other side of the mounting platform opposite the heating element; the heating element has a hollow inner cavity.

[0006] Furthermore, the sensor has an air inlet; the heating element has several air guide holes on its surface; a receiving gap is formed between the heating element and the tube; the air inlet, the mounting platform, the hollow inner cavity, and the receiving gap form an airflow channel.

[0007] Furthermore, the filter segment includes a filter head and filter packing; an adsorption plate is provided inside the filter head; the adsorption plate has a plurality of adsorption ports; the adsorption ports are irregularly shaped.

[0008] Furthermore, the heat insulation component is cylindrical; the heat insulation component is coaxially disposed inside the heating body and is tightly connected to the heating body; the heat insulation component is made of heat insulation material.

[0009] Furthermore, one end of the heat insulation component is connected to the adsorption plate; the other end of the heat insulation component is away from the mounting platform; and the end of the heating element is away from the filter head.

[0010] This utility model has the following advantages: the filter head is connected to the heat insulation component via an adsorption plate, and the heating element is then sleeved on the outside of the heat insulation component. The advantages of this design are: firstly, the heating element and the filter head are separated from each other rather than in direct contact. When the heating element is working, the heating element, which is at a higher temperature, will not directly transfer the temperature to the filter head, effectively protecting the filter head and its filler; at the same time, the heating element is connected to the inside of the filter head via the heat insulation component, and the other end is limited by the mounting platform, without relying on the tobacco wrapping for limitation, thus making it more reliable.

[0011] Secondly, since the heating element in this invention is completely encased in tobacco, all the heat it generates will be absorbed by the tobacco, reducing heat loss. Compared with the prior art, which attaches the heating element to the inner wall of the tube, this design can effectively reduce losses. Attached Figure Description

[0019] Furthermore, the sensor 3-1 has an air inlet; the heating element 3-2 has several air guide holes 3-21 on its surface; a receiving gap 5 is formed between the heating element 3-2 and the tube 1; the air inlet, the mounting platform 3-3, the hollow inner cavity and the receiving gap 5 form an airflow channel.

[0020] Specifically, air enters through the air inlet of sensor 3-1, passes through the hollow inner cavity of mounting platform 3-3 and heating element 3-2, and enters the receiving gap 5; it is then drawn in through the tobacco and from the filter section. When air enters sensor 3-1, sensor 3-1 is affected by negative pressure, which will control the heating element 3-2 to heat up. At the same time, mounting platform 3-3 can limit one end of heating element 3-2, while the other end of heating element 3-2 is limited by heat insulation, as follows:

[0021] Furthermore, the filter segment 2 includes a filter head 2-1 and filter packing; an adsorption plate 2-2 is provided inside the filter head 2-1; the adsorption plate 2-2 has a plurality of adsorption ports 2-21; the adsorption ports 2-21 are irregular in shape.

[0022] Furthermore, the heat insulation component 4 is cylindrical; the heat insulation component 4 is coaxially disposed inside the heating body 3-2 and is tightly connected to the heating body 3-2; the heat insulation component 4 is made of heat insulation material.

[0023] Furthermore, one end of the heat insulation component 4 is connected to the adsorption plate 2-2; the other end of the heat insulation component 4 is away from the mounting platform 3-3; and the end of the heating element 3-2 is away from the filter head 2-1.

[0024] In this embodiment, the other end of the heating element 3-2 is sleeved on the outside of the heat insulation member 4; while the heat insulation member 4 is connected to the adsorption plate 2-2 inside the filter head 2-1, thereby the heat insulation member 4 can support the heating element 3-2. At the same time, the end of the heating element 3-2 is far away from the filter head 2-1, and its temperature cannot be directly transferred to the filter head 2-1.

[0025] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
